AMR is still a great piece of software for getting article links, which are still good to have in your overall SEO plan.
Personally, I don't think you need to hit 1000s of smaller directories like AMR provides, I've found that just hitting a few dozen of the top sites can help work wonders. In that case, you can get a tool more specialized to just target the top main article directories.
Everyone has different opinions, that's just what I've seen after testing different approaches.
